A device API
endpoint was missing access controls on Western Digital My Cloud OS 5 iOS and Anroid Mobile Apps, My Cloud Home iOS and Android Mobile Apps, SanDisk ibi iOS and Android Mobile Apps, My Cloud OS 5 Web App, My Cloud Home Web App and the SanDisk ibi Web App. Due to a permissive CORS policy
and missing authentication requirement for private IPs, a remote attacker on
the same network as the device could obtain device information by convincing a
victim user to visit an attacker-controlled server and issue a cross-site
request.
This issue affects
